LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 241,418, dated May 10,1881.

Application filed March 18, 1881.

To all whom it may concern.-

Be it known that I, ELIAS B. REQUA, a eitizen of the United States,residing at Jersey City, in the county of Hudson and State of NewJersey, have invented new and useful Im pro vements in Lamp-Burners, ofwhich the follow- 1 ing is a specification.

The present invention relates to that class of l lamp-burners which donot require chimneys,

and is particularly intended as an improvement upon theburner formingthe subject-matter of Letters Patent No. 219,766, issued to myself onthe 16th day of September, 1879.

The object ofv the invention is to supply an increased amount of air tothe flame and interior of the burner for effecting a more perfectcombustion and insuring a brilliant and uni- 1 form light, and,furthermore, for reducing the temperature at thelower end ofthewick-tube, 1

so that the latter and the collar of the oil-fount will be preserved ina cool state, so that the 1 oil will not vaporize until it has wellascended 5 through the wick-tube.

Another object of the invention is to reduce ary manner.

I attain the results above stated by the construction and combination ofparts hereinafter described and claimed.

In the accompanying drawings, Figure l is aview in elevation of alamp-burner constructed according to the present invention. Fig. 2 is acentral vertical section thereof. Fig. 3 is a detached view of theburner-base, lower deflector, and wick-tube, having oil-suppl y opening.Fig. 4 is a detached view of the fluted foraminous shell, the central orintermediate .cone, the hinged top cone, and glass deflector- Fig. 5represents a modified form of holder. wick-tube having two screw-necks.

The letter A designates the wicktube, which has a screw-threaded neck atits lower end, formed ofthe metal composing the tube, for attachin g itto the screw-collar of the oil-fount.

(ModeL) Said wick-tube has outwardly-projecting horizontal arms a, towhich the flanged base-plate B of the burner is attached. Thisbase-plate is provided with a deflector or cone, 0,. on its upper side,which serves to conduct the air admitted below the base-plate to thewick-tube, passing upwardly thro'ughsaid deflector. The arms a areperforated, so as to offer no impediment to the free upward passage ofthe air. The wick-tube is provided with a housing or semi-cylindricalshell, D, which incloses the customary ratchet-wheels, (I, or otherdevicefor raising and lowering the wick. The shaft E of the wick-raising wheels is journaled in said housing, and the latter is arrangedimmediately above the base-plate of the burner, so as to place it atsome distance above the base of the wick-tube and the oil-fount. Thewickraising wheels project through slots in the wick-tube for properlyengaging with the Wick. The location of the wick-raising wheelsimmediately below the burner-base or at some distance above the bottomof the wicktube will obviate the jamming of the wick in the tube, whichlatter result, is sure to take place when the wick raising wheels arearranged at the bottom of the wick-tube. An enlargement or chamber, a isformed in the wick-tube directly above the screw or attaching-neckthereof. This chamber has an opening which is closed by means of a slideor cover, b. By uncovering said opening the spout of an oil-can can beinserted into the same for the purpose of filling the lanip-fount withoil at any time.

The body of the burner is made separate from the base portion thereof,and consists of the lower flanged ring,F, the fluted and foraminousshell G, and the upper plate, H, formed or provided with theupwardly-projectin g cone 1. The upper plate, H, has adownwardly-projecting flange, h, which extends below the upper end ofthe foraminous shell G, and serves as a means for holding the same andinterceptin g the upward passage of the air passing through the verticalchannels of the fluted foraminous shell, so as to cause said air to passthrough said shell and enter the interior of the cone I. Said cone has aseries ofopenings at which is composed of the vertical ring J, the

horizontal plate or support K for the detachable glass deflector orflame-protector S, and the upper metallic or brass deflector, L, of theburner. The ring J is perforated around its entire circumference, andthe plate K is also perforated thoughout its entire area. The plate Khas the customary edge rim, L and a screw or other device for retainingthe transparent flame-protector S. The lower plate, F, of the body ofthe burner has a vertical or downwardly-extending ring or flange, f,which fits on the flanged burner-base B, and the two parts are connectedby means of a bayonetjoint or other form of joint, serving to effect adetachable connection between the body of the burner and its baseportion.

It will be manifest that the fluted shell presents a large area to catchan increased amount of air, and the latter, in movingabout the channelsand ribs or fluted portions, is intercepted and compelled to pass intothe burner, instead of passing around the shell, as would be the case ifthe same were made with a plane outer surface.

The inner edges of the ribs, formed by fluting or corrugatin g theshell, extend nearly to the walls of the cone I, and thus it will beobvious that as the air ascends along the fluted foraminous shell thedownwardly-projecting flange h of the top plate, H, will arrest orintercept the upward passage of the air and cause it to passinto theinterior of the cone I.

The plate K intercepts the air as it rises, and a portion of the same isdrawn in at the perforations of the ring J and conveyed to the flame.This result would not take place if the plate K were made imperforate.The transparent flame-protector supported upon the plate K is suppliedwith air through the perforations in said plate, and in this manner thebrilliancy of the flame is further increased.

The position of the plate K at the top of the burner will enable almostthe entire portion thereof to be exposed to the air, which will insurethe production of a brilliant and uniform flame.

Itis not necessary to the successful operation of theburner to use theglass flame-protector or cone, which takes the place of the ordinarychimney; but ample provision is made for sup porting the same andfeeding air into the interior thereof. An additional reason formaintaining the perforated plate K in an elevated position, incontradistinction to being located at the base of the burner, is tocause the air in its upward progress, when the oil is burning, to strikeagainst the under side of the plate, when it is checked by those partsof the plate between the perforations, and the air then goes directlyonto the flame over the cone.

As a modification of the wick-tube and fillin g device heretoforedescribed, I contemplate using a wick-tube which has a filling-chamber,M, at its lower end, that is provided with two screw-threaded necks ofvarying diameters, so

as to enable a burner having such a wick-tube to be fitted into lamp-founts provided with different-sized collars. The filling-chamber, inthe present instance, has an upwardly-extend ing nipple, which receivesa screw-threaded plug or cap. A wick-tube of the description justspecified has its wick-raising shaft titted in the cone-shaped shell,which is firmly connected with the wick-tube, so as to leave no openingbetween it and said tube. Projections or lugs 0 serve to receive andretain the baseplate of the burner.

I am aware that a lamp-burner has been provided with acorrugatedforaminous casing, to prevent agitation of the flame in movingthe lamp, and such, broadly, I do not claim; and I am also aware thatlamp-burners have been provided with intermediate removable collars, bywhich a single burnercan be applied to lampcollars of different size;but neither do I claim such construction.

What I claim is- 1. The burner base-plate provided with an open bottomand a wick-tube extended downward, and provided atits lower end withmeans, as described, to connect it with a lamp-collar, in combinationwith a channeled or fluted foraminous shell, provided at its upper endwith a plate carrying both the perforated cone and the perforatedexterior deflector, all substantially as described.

2. The combination, with the flanged burner base-plate, having awick-tube provided with a screw-neck to connect with a lamp-collar, of100 the channeled or fluted foraminous shell, havin g at its lower endthe flanged ring F, detachably connected with the flange of the burnerbase-plate, and at its upper end provided with the flanged plate H,carrying the movable perforated deflector and the stationary perforatedcone I, substantially as described.

3. The burner base-plate B, having perforated radial arms a, andcarrying an attached air-deflecting cone, 0, in combination with thechanneled or fluted foraminous shell G, surrounding and extending abovethe air-deflecting cone, and carrying at its upper end the perforatedcone I and perforated deflector L,

substantially as described.

4. The combination, with the burner baseplate provided with the cone 0,constructed with a wick-tube projecting downwardly, and provided withmeans to support it on a lampcollar, and having the perforated arms a,of the channeled or fluted foraminous shell, de-
